To all-whom it may concern:

Be it known that I, Jason C. Srmnns, a residing at Worcester, in the county of Worcester and State of Massachusetts,-have invented a new and useful Combined Tonneau and Trouble Lamp, of which the following is a specification.

. This invention relates to a tonneau lamp for automobiles so constructed as to be capable of use in an efiicient and convenient manner as a-trouble lamp.

The object of this invention is to provide simple and inexpensive detachable devices by which the lamp can be so mounted as to be able to accomplish both of these results and it involves special provisions for that purpose as will appear.

Reference is to be had to the accompanying drawings in which- I Figure 1 is a perspective view of a tonneau lamp shown in position on the wall of a tonneau and constructed in accordance with the present invention;

Fig. 2 is an elevation'of the lain support,

ing and attaching ring showing t e reverse side, with the lamp in position therein;

Fig. 3 is a sectional view on the line 3-3 of Fig. 2'; y

Fig. 4 is a view similar to Fig. a modified construction and Fig. 5 is a sectional new. on the line 5-5 of Fig. 4. a Referring first to the first three figures it will be seen that when the lamp 10 is in place on the wall 11 of the tonneau, whether it is the front wall or otherwise, it has the appearance of the usual tonneau lamp, being supported by a surrounding ring nected with the 'wall of the tonneau by screws 13 or the like. However, beyond the wall 11 there is a space in which a coil or at least a length of electric light cable 14 connected with the-lamp can be stored. This cable, of course, isconnected u with any usual source of power to supply e lamp.

Although the ring 12 is of the usual appearance outside it is formed with a circular projection 15 concentric with the lamp and furnishing a flat wall against which the 2 showing flange of the lamp rests, and a recess under Specification 0!

almostentirely surrounding the lamp inside the mg 12 but not of circular shape; It is shown in the present case the ring by three cli wire passes and having its ends 18 separated from each other to allow for expansion and contraction. This wire spring is also fiattened in three places 19 between the clips 17 so that these the circumferentialgroove 20 in the rear body 21 of the lamp. f

The parts being assembled, as'shown in Figs. 1, 2 and 3, the-lamp serves ordinarily as the usual tonneau lamp, but when it is desired to use it for a. trouble lamp it is pulled out by the application ofpressure to release it from the s ring 16. This can be accompllshed by ta g hold of the flange of the lamp and pulling it directly out, or if that does not release it, tipping it first in one direction and then in the other. The leverage thus secured releases it from the spring. Then the lamp can be handled in a very convenient way and used as long as may be desired within the car or near it. The coil of \wire 14, of course, permits of this action. When it is desiredto return it the wire is first tucked in beyond the wall 11 and then the lamp forced into place by merely pushing it backward in the ring 12.

In the form shown in Figs. 4 and 5 the same operation and the same principles are retained, but the lamp itself instead of the groove 20 is provided with a circumferential head or lprojection 25 and the inside of the mug 26 as'three spring clips 27, each one having a tongue 28 provided with a recess 29 for receiving the bead .25. For convenience these clips may be secured to the ring by receive the screws 13 shown in Fig.1. The

results are substantially-the same as in the Patented July as, ieie.

as supported from ps 17 through which the 1 -eint case consists of a single piece of" Wire flattened portions will engage other figures, and its uses and operation need not be described in detail.

Althou 'h-I have illustrated and described only two orms of the invention I am aware of the fact that many modifications can be made therein without departing from the scope of the invention as expressed in theclaim. Therefore I do not wish be limi ted to all the details of construction herein shown and described but what I do claim 1s: v

The combination with a supporting ring mounted on the vertical Wall of an automo- 5 bile and substantially flush with the surface thereof and having a central passage therethrough, of a tonneau lamp adapted to be supported within said ring and passage and beyond said wall, the front surface of the lamp lying substantially in the plane of said 10 ring, and 'eldin means within the ring for detacha ly hol g the lamp therein but
